hi all i am looking for a 100 series petrol landcruiser 2uz but i am not sure if maybe i should be looking at a 1hz, are they as bad as what people are saying when it comes to towing
as a stock car mainly for the fuel consumption i am not worried about going fast so its more about being reliable.

What are you towing? They will go forever, but you'll have a hard time maintaining 100km/h with anything more than a very light weight box trailer

ha ha how many ks out of v8
23 litres per hundred at 95km/h.

I was previously towing 1.6 tonne van with a diesel Mazda 6 wagon and did 12.5 litres average at 100km/h... But it was a modern and powerful diesel.

Petrols are thirsty but it's painful towing at 80km/h in 3rd gear with your foot planted to the floor in your ancient tractor diesel.

If you aren’t worried about going fast it will be perfect for you. Just not anyone you are sharing the road with. The pre anti pollution 1hz is the more reliable version I am lead to believe. I don’t miss driving them.

Very hit an miss with a turbo on a 1hz. The piston were not made for the extra heat. For long life out of the 1Hz I wouldn't be putting a turbo on special with the km most likely on the clock. But if you do and do it correctly the cost factor would most likely now put you into a early 100series with a decent 1hd fte. (awesome motor).

I had a 1hz brought 2nd already "turboed". it went well for what it was, untill she absolutely poo ed itself.

They are a chug chug along 4wd. slow and relaxing is the go. See a big hill, specially towing just slow down and enjoy the view.

By the time you mess around with a turbo you may as well have purchased something else. Unless the motor is well cared for and the install done very well, you will eventually have issues. There are hundreds of bad stories out there about turbo'd 1HZ motors

awesome guys thanks for all your help.i might look at a 1hd-fte and see if there are any out there that have ok ks.
also on a side note are the toyota motors any good for gas.

If you're not set on a Toyota have a look at TD42t Patrol's (yes I am a little biased). The 1hd-FTE is a probably a slightly nicer engine but its not as far ahead as the price would suggest. Mine is bone stock aside from a 3 inch exhaust and it has no problems towing an approximately 1.5 ton boat while turning 33s. As long as you don't go chasing huge power with them they are just as reliable also

I've had a few LPG cars, most with high quality high performance systems not basic draw through ring systems or simple diaphragm systems. With that said I would not put LPG on a car like this for many reasons. I don't say this to imply anything about your income but if fuel cost is a concern for you, a LandCruiser Petrol is not a good choice.

yes i do understand what you are saying about the petrol LC,i have seen a few cars with lpg and hear a lot of different comments on them.
and RDM i did look at the td42 but the boss wants a Toyota as we are a Toyota family ha ha all my kids have them.
i have a 2010 (150) 1kd Prado that i am selling and i wand a bigger tow car.

As for turbocharging a 1hz it may be ok but all the connecting parts will fall apart

the 1HD has a decent drivetrain the old 1HZs not so much

IMO it would be a different situation if you could pick up a dual fuel one, already converted and not due for a LPG tank retest soon. If the conversion has been done correctly I wouldn't imagine you would have problems with a 100 series. The conversion I would be looking for would be an LPG tank that did not involve reducing the size of the original petrol tank, so you get the benefits of extended km's between fuel fill ups.
I fitted LPG to an FJ60 LandCruiser back in 1992 and drove it 270,000 km's over the following 14 years all over Australia (plenty of outback, desert and Pilbara trips in that time).
I wouldn't bother fitting LPG these days, because LPG has gone out of fashion (vehicle manufacturers and service stations getting out of it). It's a pity as it is an environmentally clean fuel.

Poor availability, lack of specialist support anymore, reductions in ground clearance, compromises in ignition timing, cheap systems utilise intake tract reducing rings or mixers,back fires and blown air boxes, good systems have injectors but still LPG occupies 1/3 of the available airspace in the intake tract which reduces available oxygen by the same amount and negates any power picked up by more aggressive timing and so on and so on. Sooo many factors most owners never consider, and like you say Colly especially if not already installed there's a massive possibility of creating false economy installing a very costly system.
